Fellow arrow followers, Regarding any concrete arrow that may have been at the airway beacon site north of Wendover: For the life of me I cannot understand why there would be a concrete navigation arrow on top of a peak marked with a flashing red warning beacon that implies, Warning: Do not fly into this mountain. A description of that beacon and its function is in the survey information listed for that site in the GIS Arrow Project interactive map at https://sites.google.com/site/gisarrowproject/interactive-map This particular beacon, while on the list of beacons (but not numbered) for the SFO-SLC airway is not on the obvious flight path from Wendover airport (where the previous beacon #52 was located) and the Salduro beacon #53 which was the next beacon east of Wendover. I don't think this site was ever intended to be over flown on the SFO-SLC airway and therefore would not have had a concrete arrow installed. Ed Stimpson
